I confess that I really admire the courage of the Jehovah's Witnesses and the Mormons. They always seem to show up when I am having a crazy morning and often when I have the 'flu. The gentlemen who turned up today were very kind, understood that this was not a good day, handed me some literature and left.
I know that the men and women who come door to door do it out of deep belief, and I know that they get countless doors slammed in their faces, plenty of invective and more than a few people who play mind games with them. They do it anyway.
